How to distinguish the authenticity and quality of biostimulant products?
"What are the effects of biostimulant products?"

Question 1: What is a biostimulant?
There have been differences in the names of biostimulants, such as: plant growth promoters, bioactive agents, plant growth promoters, soil improvers, growth regulators, etc., but these names are not accurate enough.

The definition of the European Biostimulant Industry Alliance is: Plant biostimulant is a substance containing certain ingredients and microorganisms. When these ingredients and microorganisms are applied around the root system of plants, their effect is to stimulate the natural processes of plants, including enhancing/benefiting nutrient absorption, nutritional efficacy, abiotic stress resistance and crop quality, and has nothing to do with nutritional ingredients.

The American Biostimulant Alliance believes that biostimulants are substances that, when applied to crops, seeds, soil or growth media, have the same effect as existing Combined with the fertilization plan, it can improve the efficiency of crop nutrient application, or provide other direct or indirect benefits to crop growth and stress response. It can be divided into several categories, such as microbial agents, amino acids, humic acid, fulvic acid, and seaweed extracts.

The current mainstream understanding of biostimulants in China is that the target of biostimulants is the crops themselves. It can improve the physiological and biochemical state of plants, improve the effectiveness of pesticides and the utilization rate of fertilizers, and improve the level of crop resistance to adversity. Of course, biostimulants also improve the final yield of crops and the quality of agricultural products. Biostimulants are generally divided into 8 categories: humic acid, complex organic materials, beneficial chemical elements, inorganic salts (including phosphites), seaweed extracts, chitin and chitosan derivatives, anti-transpiration agents, free amino acids and other nitrogen-containing substances.

Q2: Is biostimulant a pesticide or a fertilizer?
Biostimulant is neither completely a fertilizer nor a pesticide. It is on the edge of fertilizers and pesticides. Currently, plant growth regulators in pesticides and functional fertilizers in fertilizers can all be classified as biostimulants.

Q3: Is biostimulant a hormone?
There are obvious differences between biostimulants and hormones: biostimulants are inherent in crops and can be synthesized by themselves, while hormones are usually processed using certain production processes; biostimulant products can indirectly promote plant growth. Usually, excessive use will not cause much harm, while hormone products will cause great harm if used improperly. Therefore, biostimulants cannot be simply called hormones.

Q4: What effect does biostimulant have on crops?

There is a big difference between biostimulants and traditional crop nutrition, and it is even different from conventional fertilizers. Biostimulants act on crops through different mechanisms, and it is not important whether the product contains nutrients. Biostimulant is different from plant protection agent. Biostimulant only acts on the growth vitality of crops and obtains systemic disease resistance. It has no direct killing effect on pests and diseases. In crop planting, biostimulant plays a synergistic role with nutrition and plant protection agents. The three work together to maintain the healthy growth of crops.

1) Extreme temperature, irregular rainfall and climate change and other stress environments are happening more and more, which puts higher and higher requirements on the normal growth of crops. Biostimulant can increase plant resistance and resist the stress of abiotic factors.

2 Biostimulant has the ability to regulate water in plants, which helps crops survive under drought conditions.

3) Biostimulant promotes the absorption, movement and use of nutrients, thereby avoiding the leaching or loss of nutrients to neighboring ecosystems. Reducing nutrient losses means that crops can make better use of natural resources.

4) Biostimulant can improve the quality attributes of agricultural products, such as sugar content, coloring, sowing quality, etc. Providing consumers with better storage and more nutritious agricultural products means higher income.

5) Biostimulant helps improve the physical and chemical properties of the soil, promotes the development of beneficial soil microorganisms, and protects and improves soil health. Healthy soil retains water better and can better resist soil erosion.

The effect of biostimulant on crops depends on the type of crop, the original state of the soil, the planting conditions of the crop, and other factors.
